Given that there would not appear to be any "official" Load Data in existence for this Load, can several of you offer a starting point with this mix and things to think about when working this Load up?
Needless to say, the Hodgdon tech would not endorse my mixing of different large amount figures, but I do think I understand why. It is a litigation-driven planet, and a few fool would certainly deduce that he could blend H380 and H110 and come up with his individual customized blend of powder. What a environment.
The most obvious induce is actually a tough/ruff bore. No number of copper fouling lowering brokers from the powder will appropriate this.
Warning using SC or SSC created loads with extended Lower, back again off and operate up. Use Risk-free loading techniques.
My working experience is that the SC and SSC loaded to exactly the same pounds because the prolonged cut demonstrates a reduced velocity.
I am aware, tough times. H4831SC will certainly do the job, I just failed to like the situation density when loaded prolonged. I don't bear in mind powder charge off the top of my head but I had been launching a Berger 168gr VLD at 3,000fps which is where I usually purpose being. As part of your situation using what you've (and what I h4831sc should have carried out) I'd personally begin with the end of the bearing area on the bullet proper in the shoulder/neck junction, and flirt with extending seating depths from there once you find a velocity node.
I don't like to operate up a load making use of one particular lots of powder and afterwards have to operate up yet again simply because I operate out and also have to start out h4831sc load data using a new large amount amount.
Anyhow, I wanted to give some 7828SC a attempt to cut down many of the compression. What a miscalculation, I could not get this powder h4831sc load data to shoot correctly or create the velocities I get with conventional 7828.
Along with the shorter Lower Edition powder arrives approximately the base in the decrease shoulder so I even now have a great deal of area.
locutus stated: I nonetheless have a good stockpile of H450, the ball powder equal of 4831, which flows by my powder actions smoothly.
Run your load up with the particular powder (sc or common) and lot you might be employing while. Same burn price doesn't mean it's going to behave "just" a similar. I have found over 100 fps distinction between sc and mil-surp lots of H4831.
Sure, You should utilize precisely the same load data for H4831 vs H4831SC, though the SC version may possibly assist you to get a little far more in cases in which you are maxing out case volume With all the typical powder right before achieving pressure limits.
Several of the aged Lyman data just outlined IMR 4831, which was surplus military powder and now more recent mfg as H4831.
Obviously, sitting down all around for 20+ a long time (I realize a man who continues to be utilizing the H4831 he purchased in the 60s), signifies that burn up fees will probably improve a smidge, and new manufacture stuff will likely be a bit different far too.
